Sure costs would plateau eventually but it would still be at a level which is not affordable for the majority of the field.
You assume that the teams would have to buy or partially subsidise their tyres and yet elsewhere it has been said that to be involved today costs Michelin as the teams do not purchase tyres etc.
My belief is quite simple, and that is that the teams would not need to buy tyres as there will be tyre manufacturers who will want to be involved with specific teams or riders and through smart contractual negotiations, the team will be charged zilch as the trade off if successful is that the tyre company will increase market share. Of course, this will work where the tyre manufacturer wishes to work with or sponsor the team involved and there may be occasions or situations where 'lesser' teams may need to subsidise or encourage the tyre company (which can be done by increasing of size of fonts and awareness etc)
Tyres in demand would perhaps be manufactured in larger volumes and be cheaper but that also means that more exotic builds would be more expensive putting riders & teams that prefer it at a disadvantage.
True but again, the chances of one-off exotic builds for a single rider would be less as if the rider is high profile (let us use Marquez for example), then many will want that tyre and will simply adjust themselves (the old, if he can do it approach).
For riders of lesser profile or capability, if that is the only tyre that works, then it will be a low volume build and thus, costs are not as high (albeit, higher)
Thing is, we've been here in past. Pramac dumped its Dunlops in 2006. Tech 3 used them for a year but by 2007, they'd realized that they didn't have a future together with its riders placing last and third last in the rider standings.
Maybe that was because of a lack of will on Dunlop's part to invest in remaining competitive, maybe it was something else. In either case, sponsoring the tailenders wasn't exactly great advertising for its product and its exit from the class was more or less inevitable.
Just because it had issues once does not mean that it will today plus, the period you mention is during the GFC where dollar investment was reducing and the end result was the whinge and control tyres.
Conversely, it did work for Bridgestone to target a smaller team and build with that team, so for every diamond, there is a turd so to speak but we should not dwell on turds.
As for Dunlop's will, I do vaguely (emphasis on vaguely) recall articles surrounding a change in their focus to another form of motorsports as to why they did start to drop off, but again, it also corresponded with GFC.
But to come back today, sponsor a team willing to run its tyres and also make those tyres available to rest of the field, its just not doable.
It is doable, but one needs to not expect results immediately but allow time to achieve the result.
Again also, it is not entire field but tyres available to contracted riders/teams so if they chose, they simply do not have to sponsor teams which then allows them to make tyres available for purchase (all manufacturers). This of course goes back to your first point, increasing cost of satellite teams which for mine, is a simple 'survival of the fittest' scenario as if the team is uncompetitive because they have no money, either find money or reassess targets (drop to Moto2, get results/sponsors and return for example)
Given its fairly decent prospects, would Aspar be willing to risk it all by switching to Pirellis? Would they do so next year when they receive a new batch of bikes that have been specifically designed to work with whatever tyre factory Ducatis are using?
You mentioned Aspar thus I used them as the example but why not?
There was a time when I am sure that someone at Ducati asked whether they should go with Bridgestone or use the Michelin that everyone else was using, and we know what happened there.
Point is, sometimes if a team gambles, they can win and simple good results will bring interest and often with interest comes money.
Sure Aspar or any other team can use the same tyres as everyone else but that also runs a serious risk of placing them as one of the flock rather than the black sheep out there getting noticed.
This takes us back to square one where every rider is forced to use the tyre that his team is contracted for.
Which is no different to today.
Riders have to use tyres that they have had little to no input in developing and that have been shown to cause unexpected results (front end loses) and/or have negative effects on bike setup compared to tyres that were tested.
Rossi, Lorenzo, Marquez get their say in how the tyre evolves (since the supplier is interested in getting those wins & podiums) while Folger, Redding & Miller are forced to use what they're given (since the supplier is less interested in top 10 finishes).
Which is the large issue I have and always have since the single supply (as if you haven't guessed, I believe in prototype to mean prototype, not spec this, prototype that), the tyres used today are built for a small number of people, so my desire and belief is increase that number of people by building more tyres (if that makes sense)
